Hi,
Either you need to remove the record that have a zero, in that case, use a
delete query,
either you need to remove the 0 appearing at the extreme left of a number.
That occurs if you number is, in fact, a STRING (check the data type of the
field), either you "see" a formatted number, through a format, or a mask. In
the first case, change the data type in table design; in the second case,
remove the offending format, or mask.
Hoping it may help,
